Quoted:
I heard that the 5.56 nato ammo might become lead free. Might have a solid copper bullet. Price would be much higher. Would solid copper be armor pearcing? If so, would it be banned from the civilian market as a result? Hi, The only way copper would be banned from the civilian market for 5.56 NATO ammo is if somebody added enough of another metal like tin to it to make it bronze, or one of the other banned alloys.

M855A1 is already in use...
 some European countries have been using lead free ammo for years |

I think the OP may have been concerned about the ban on pistol bullets with 25% or more of their weight in a copper jacket?
the law also bans use of beryllium copper, which is "high hardness" copper, not gilding metal. M855A1 would have to have a 15.5 grain jacket to be 25% copper if it was determined to be a pistol bullet. The steel ogive is 20 grains I think. I dont think the jacket will be quite 25%. But if it is, the Gun grabbers will interpret it that way. |

The problem with all copper is that it isn't nearly as heavy as lead, nor as malleable. So what would be a good replacement for lead (Pb)? Look to the right of it one spot on the Periodic Table of Elements and you'll see Bismuth, which is about the same atomic weight.
It would make more sense to me to use Bismuth as the core, and maintain a steel penetrator, than to go all copper, and that's exactly what is shown here: Http://www.thefirearmblog.com/blog/2010/07/02/u-s-army-issues-new-green-m855a1-ammo/

If so, would it be banned from the civilian market as a result? Solid copper is not one of the metals listed in the rules that qualifies bullets as AP. On the other hand, beryllium copper, which is a much tougher alloy than plain copper, IS on that list. Solid copper has a couple of drawbacks for bullet manufacture. First, it isn't nearly dense enough to deliver kinetic energy to the target without substantial decrease in range. And while there are already copper bullets on the market, including solid copper handgun bullets, they take advantage of the inherent softness of copper to be effective. That pretty much eliminates "solid copper" from being useful as a military bullet, since the soft copper would deform without penetrating appropriately in military-type rounds. The current lead-free 5.56mm lead-free bullets in use have a number of issues in the field. There is little reason to worry that these bullets will be an issue for civilians. |

Well, if that's the case then I won't be able to shoot either of my ARs because I can't shoot any metal core bullets at my range...or any range that I know of.

I already use solid copper bullets for my 30-06 elk rifle, better ballistics. yea and f all the hippie libitard tree hungers that want to ban lead...and FBHO for good measure :) |

THE SDZs for anything firing M855A1 ball ammunition are much more impressive (in terms of max range) than those for the older M855.
Everything I've read about the new round makes me believe it will be better than its predecessors. OTOH, some SOCOM assets still utilize M193 for whatever reason..... |

From what I've seen, a lot better at penetration. It shreds backstops and steel plates that 855 doesn't do shit to. It's rough on bore erosion though, and I've seen an increase in broken bolt lugs. |

Cracks in the bolt have been documented around 3k of shooting M855A1. Increase length of the bullet and higher pressure will do that. |
